As shown in FIG. 2 , the satellite communication method according to an embodiment of the present disclosure includes the following processing steps:
步骤201，核心网经由星间链路或星内链路通过第一通信卫星与用户设备UE进行通信。
在本公开实施例中，将核心网和业务服务器均设置于星际空间，即将核心网和业务服务器均设置于通信卫星上，当卫星终端或用户设备通过地面站与接入卫星通信时，接入卫星接收到接入通信信号后，直接在星际间为用户设备进行通信接入，不必再将用户设备的通信请求转向地面的核心网中进行处理，从而缩短了卫星通信的连接链路，从而提升卫星通信系统的通信质量。In the embodiment of the present disclosure, both the core network and the service server are set in the interstellar space, that is, both the core network and the service server are set on the communication satellite. When the satellite terminal or user equipment communicates with the access satellite through the ground station, the access satellite After the satellite receives the access communication signal, it directly communicates with the user equipment between the stars, and it is no longer necessary to transfer the communication request of the user equipment to the core network on the ground for processing, thus shortening the connection link of satellite communication, thereby improving the Communication quality of satellite communication systems.
在本公开实施例中，所述星内链路为在位于同一个通信卫星内的通信接口或数据接口之间建立的连接链路。In the embodiment of the present disclosure, the intra-satellite link is a connection link established between communication interfaces or data interfaces located in the same communication satellite.

The UE or satellite terminal sends the response. Here, the first communication satellite serves as the access satellite of the UE or the satellite terminal, and receives the communication request sent by the satellite terminal or the communication request of the UE forwarded by the satellite ground station.
作为一种实现方式，所述通信请求中携带有目标UE或目标卫星终端的标识信息；所述核心网基于所述通信请求，确定所述UE或卫星终端的标识需与所述目标UE或目标卫星终端的标识建立连接时，查找所述目标UE或目标卫星终端接入的目标通信卫星，通过星间链路或星内链路将所述通信请求向所述目标通信卫星转发，并在接收到所述目标通信卫星转发的所述目标UE或目标卫星终端的同意建立通信连接的响应后，使所述UE或卫星终端与所述目标UE或目标卫星终端之间建立通信链路。本公开实施例中，所述目标通信卫星可以为第一通信卫星，此时，所述目标UE或目标卫星终端与通信请求发起的UE或卫星终端均在第一通信卫星覆盖下的接入范围内。当然，目标通信卫星也可以是不同于第一通信卫星的其他通信卫星。As an implementation manner, the communication request carries the identification information of the target UE or the target satellite terminal; the core network determines, based on the communication request, that the identification of the UE or the satellite terminal needs to be associated with the target UE or the target satellite terminal. When the identification of the satellite terminal establishes a connection, it searches for the target communication satellite to which the target UE or the target satellite terminal is connected, and forwards the communication request to the target communication satellite through the inter-satellite link or the intra-satellite link, and when receiving After receiving the response from the target UE or the target satellite terminal forwarded by the target communication satellite for agreeing to establish a communication connection, a communication link is established between the UE or the satellite terminal and the target UE or the target satellite terminal. In the embodiment of the present disclosure, the target communication satellite may be the first communication satellite. In this case, the target UE or the target satellite terminal and the UE or satellite terminal that initiates the communication request are both within the access range covered by the first communication satellite. Inside. Of course, the target communication satellite may also be other communication satellites different from the first communication satellite.
